Bill O'Reilly may have had one last card to play to save his job at Fox News

Jamie McCarthy/Getty Images for The Rumble 2012 An email from a Democratic Party operative may have been Bill O'Reilly's last play to save his job at Fox News amid a growing sexual-harassment scandal.

O'Reilly and his representatives circulated an email from a Democratic fundraiser who supported the liberal-leaning watchdog Media Matters.

Politico reported that the email announced some coming conference calls set for this week in which people associated with Media Matters would discuss its efforts to get advertisers to abandon O'Reilly's Fox News program, "The O'Reilly Factor."

The so-called Stop O'Reilly campaign was well-publicized on social media, with the help of Media Matters' president, Angelo Carusone, who spearheaded similar grassroots efforts targeting former Fox News host Glenn Beck.

According to Politico, O'Reilly saw Media Matters' effort as a politically motivated, "left-wing plot" to get him fired, but he stopped short of bringing that email to the attention of 21st Century Fox executives. According to Politico's Joe Pompeo, who saw a Tuesday email exchange between O'Reilly and his representatives, O'Reilly is said to have wrote, "If we show to Fox tomorrow, word will get out and the Thursday call may be cancelled."

In the email, O'Reilly himself had apparently also run out of patience with Fox News Channel, the network he had called home for 20 years: "You all should know that I will not put up with much more from FNC," he wrote.
